Ok, so presumably it's the SHA1 chksum that it doesn't like:
joshua-fd: filed/accurate.c:236-0 add
fname=<C:/Users/Dan/Perl/from_linux/comments/block/block_ip.txt> lstat=A
A IH/ B A A A A A A BJ7e3Q BJ7e3Q BJ7e3Q A A M delta_seq=0
chksum=wUJerN1ZDJwRrMXpKcXmVly9OL8
...
joshua-fd: filed/accurate.c:82-0 lookup
<C:/Users/Dan/Perl/from_linux/comments/block/block_ip.txt> ok
joshua-fd: filed/verify.c:297-0 === digest_file
joshua-fd: filed/accurate.c:453-0
C:/Users/Dan/Perl/from_linux/comments/block/block_ip.txt SHA1
chksum diff. Cat: wUJerN1ZDJwRrMXpKcXmVly9OL8 File:
2jmj7l5rSw0yVb/vlWAYkK/YBwk
joshua-fd: findlib/bfile.c:529-0 === NO plugin
joshua-fd: findlib/bfile.c:621-0 Read
CreateFileW=\\?\GLOBALROOT\Device\HarddiskVolumeShadowCopy21\Users\Dan\Perl\from_linux\comments\block\block_ip.txt
So I guess I'll just try it with MD5's for that client on my next
scheduled full backup and see what happens after that.
Cheers,
Dan
